Bindings are a small piece of equipment which automatically releases the boots from the skis in the event of a crash.

If they failed it could have meant Schumacher’s skis were released unnecessarily causing him to lose control.

It also emerged that he did film his horror smash on his helmet camera.

Schumacher’s GoPro camera was handed to police but it was not known if it was switched on at the time of the accident.

Today it was claimed that the video footage was usable by police and was forming a crucial part of their investigation.

Meanwhile, Schumacher’s wife Corinna has pleaded with the media to leave Grenoble University Hospital where he is being treated.

In a statement Corinna said: “Please support us in our common fight for Michael. It is important to me that the doctors and the hospital be left in peace to work. Trust, please, in the doctors’ statements and leave the hospital.”
